Create a Bootable USB Flash Drive Without Any Software
Creating installation media for your operating system of
choice used to be simple. Just download an ISO and burn it to CD or DVD. Now
we’re using USB drives, and the process is a little different for each
operating system.
You can’t just copy files from an ISO disc image directly
onto your USB drive. The USB drive’s data partition needs to be made bootable,
for one thing. This process will usually wipe your USB drive or SD card.
To create a bootable USB flash drive
o
Insert a USB flash drive into a running
computer.
o
Open a Command Prompt window as an
administrator.
o
Type diskpart
o
In the new command line window that opens, to
determine the USB flash drive number or drive letter, at the command prompt,
type list disk, and then click ENTER. The list disk command displays all the
disks on the computer. Note the drive number or drive letter of the USB flash
drive.
o
At the command prompt, type select disk
<X>, where X is the drive number or drive letter of the USB flash drive,
and then click ENTER.
o
Type clean, and the click ENTER. This command
deletes all data from the USB flash drive.
o
To create a new primary partition on the USB
flash drive, type create part pri, and then click ENTER.
o
To select the partition that you just created,
type select part 1, and then click ENTER.
o
To format the partition, type format fs=ntfs
quick, and then click ENTER.
If your server
platform supports Unified Extensible Firmware Interface (UEFI), you should
format the USB flash drive as FAT32 rather than as NTFS. To format the
partition as FAT32, type format fs=fat32 quick, and then click ENTER.
o
Type active, and then click ENTER.
o
Type exit, and then click ENTER.
o
When you finish preparing your custom image,
save it to the root of the USB flash drive.
